Is this software legal/illegal for use on party?

[CakeKing]

I know there was some issues a while back when party would shut down if certain programs (bots and others) were running in the background.

Ive considered buying pokerprophecy (google will find it, dont know if linking is bad)

Also, is it worth it? im only playing 11 SnGs and pokertracker isnt worth since there is such a great turnover of players that i cant log log more than max. 1 player ever 3 sngs.
